If the original Rainbow Six Vegas felt like the first night of a trip to Sin City, its recently released sequel feels like the second; a little worn, but still a lot of fun. There's still a casino's worth of content and the best gameplay this side of Caesar's Palace. Plus, the introduction of a sprint button not only increases your speed, but also quickens the pace of the entire game. On the other hand, the cooperative play has been pared down a little and the expanded experience gains are about as glamorous as pillow mints--even if you are grateful for them. A third night of this might be too much to handle, but if you like to place bets with bullets at all, you'll definitely want to put some money down on Rainbow Six Vegas 2.
